Publication number: 20220131445Abstract: In a driving device according to the present invention, an internal space of a fixed housing provided with an electric motor and an electric circuit board configured to control drive of the electric motor is partitioned into a first chamber arranged therein with the electric motor and a second chamber arranged therein with the electric circuit board. The driving device includes a heat dissipation part configured to efficiently dissipate heat generated from the electric circuit board, from the second chamber to the outside of the fixed housing, and thus, heat generated from the electric motor is not easily transmitted to the second chamber via the fixed housing, and moisture is prevented from entering the fixed housing when outside air flows into the fixed housing.Type: ApplicationFiled: September 30, 2021Publication date: April 28, 2022Inventors: Yusuke NAKAMURA, Shigeaki NAKAGAWA, Tatsuya KAMADA, Masato ARATA, Yoshitaka KOCHIDOMARI, Kousaku KITA, Yujiro TANAKA
